VB Browser with Office documents editing toolbars

I have seen different versions of browsers coded in VB, nevertheless even those called COMPLETE or FULL VB Browser won't be able to edit an Office document when open locally.
Some of them would have the ability to open any type of document locally and even display it on the browser but none would display the necessary editing toolbars as Internet Explorer does when opening any Office type document(an icon called Tools can be clicked and the necessary toolbar would appear).
HOW CAN THIS BE DONE?
